Abstract
Abstract Solar heat tracking and collecting apparatus including a frame, means for rotating the frame in altitude and azimuth, a solar heat concentrator mounted on the frame and a solar energy sensing means disposed on the frame and operable to control the frame rotation means. The solar heat concentrator includes a substantially rectangular, flat collector plate and two pair of oppositely disposed light reflective side walls bounding the collector plate, the side walls in a converging relationship to one another. The device may also contain a triphase solar mode sensor which is operable during the full sun phase to enable and disable the solar energy sensing means from automatically controlling the frame rotation. When the sky is overcast the solar energy sensing means become inoperable and the mode sensor then operates a timer which enables the obscured sun to be accurately tracked within very close tolerances. In a third phase, the darkness phase, the mode sensor is operable to reset the frame with its mounted solar heat concentrator to a substantially horizontal, easterly direction.
